Table 2 Coefficients for changes following fire as determined by season of burning using ordinary least-squares regression (OLS) and spatial generalized least squares regression (GLS). Regression parameters (β) describe the difference of late season burning relative to early season burning. AICc values of OLS and GLS models are compared relative to the GLS model (ΔAICc _GLS ).
